At 10.73 carats, this is a MAJOR diamond thumbnail specimen for its luster, sharpness, and color saturation. The color is fancy intense, not just a medium yellow. The luster is bright and glassy, not just average. And, the geometry is more appealing than most such simple, single crystals. Moreover, most diamonds in this size show rolling dings or worn edges from natural proceesses or from damage in handling. This is a razor sharp quality for a cluster, which tend to be rounded. The locality is probably from the Miba Mine, based on style, though my source was not sure of that detail. In any case, it is a SUPERB crystallized fancy diamond crystal that stands out from the usual white and colorless singles! The crystal measures 1.1 or 1 cm on edges, and 1.5 cm tip to tip as it stands up. Joe Budd photos
